WE-G-116-1 Wednesday 4:30PM - 6:00PM Room: 116

In the last decade IMRT and related treatment modes have become de facto, if not actual standards of care. These modes are heavily dependent on the anatomical modeling phase of treatment planning. It may in fact be argued that this is the most important step in the planning process, as the optimization and plan evaluation will be directly affected by a good or poor anatomical model. We are also becoming aware that the accuracy of modeling can have a direct effect on sparing OARs. Physicists have increasingly been called upon to do much of this contouring, yet have traditionally had only a brief formal introduction to anatomy. This session will provide a brief overview and refresher on two anatomical regions that have come to be most often treated by IMRT and like modalities.

Dr. Mary Feng will discuss the contouring of prominent normal structures and target volumes in the thorax, focusing on cardiac structures, using multiple imaging modalities, and illuminate key concepts in identifying these structures. Dr John Knisely will discuss the structures in the CNS, focusing on relevance to Stereotactic treatments of the brain.

Learning Objectives:
1.To better understand how to identify structures in the thorax
2.To better understand how to identify structures in the brain and CNS
3.To understand the impact and pitfalls of different imaging modalities in these anatomical locations.
